Dish CS reps know nothing about the RV plans. The RV market is such a tiny part of their business, most CS reps will never have an RV call in their entire career.
I always and ONLY use Chat to talk to Dish. There it is easier to explain what I need. In general I try to avoid conversations with CS reps anywhere, but for Dish, I found it essential.
Now, we are full-timers, so it is something we depend upon all the time. Dish has updated the mobile app for my cell phone so I can see where the satellites are, and make sure I have a clear view of them when I try to setup the dish. I can change my location so that I get the local channels for that area - important for weather.
I might also add, if you have any television service at home, check into possible options.
AT&T has mobile plans for satellite users if people use Direct-TV at their home, or use any wired/ fiber AT&T television service.
But AT&T refuses to sell Direct-TV to people with no fixed base for their primary receiver setup. Dish is the only option for people like us who have no physical home base.
